STEAM-ENGINE.

SPECIFICATIONforming part of Letters Patent No. 415,137, dated November12, 1889.

Application led February 28, 1889. Serial No. 301,586. (No model.) Y

To all whom, it may concern:

Be it known that I7 WILLIAM E. CLARKE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Condensers forSteam-Engines, of which the following` is a specification.

This invention relates to condensers for engines and boilers; and itconsists in the combination, with the engine and boiler, of surfacecondensers joined at their tops with anl overhead dome, provided with adischargeopening having a 'fan-blower for enhancing the currents of airthrough the condensers and increasing the draft of the boiler-furnace,as hereinafter described, and pointed out in the claim.

The object of the invention is to provide a cheap and economical meansof disposing of exhaust-steam, and is particularly applicable forstreet-car steam motors.

The invention consists in the peculiarconstruction and combinations ofdevices, substantially as hereinafter described, and pointed out in theclaim.

In the accompanying drawings, Figure lis a longitudinal section of acarand motor having my improved condenser attached. Fig. 2 is a transversesection of the same.

Arepresents a car-body mounted on a truck B represents a boiler, and C asteam-engine motor. These may be of any of the well-known constructions.

D are condensers into which the steam from the engines is exhausted. Inthe drawings they are represented in the form of chambers located at thesides of the car-body for convenience of arrangement for such vehicles.They might be cylindrical in form, if desirable, in other instances ofadaptation. They are provided with open i'lues d d, extending frombottom to top, the space surrounding said flues forming thesteam-chamber and the surfaces of the flues forming the steamcondensingsurfaces. The tops of the condensers are connected with a hoodeddomeshaped chamber E,the central part at the top being provided withalarge outlet-pipe E, extending upward through the roof of the car. Inthe said pipe F is provided a rotary fan G, iixed on a vertical shaft H,having a pulley I, connected by a belt or otherwise with power from theengine for imparting rapid rotary motion to the said fan. The purpose ofthe fan is for inducing currents of cold air up through the iiues (l,whose lower ends are open to the cold outer atmosphere, their upper endsleading into the dome-chamber E.

J arepipes leading from the exhaust-ports of the engines into thecondensing-chambers,

where the steam is quickly condensed. The

water resulting from the condensation may be removed from thesecondensers by means of pumps or other suitable means to the watersupplytank for the boiler.

The front of the boiler B is also connected with the dome-chamber E, sothat the gases and other products of combustion are discharged out ofthe pipe F, and the draft of the boiler-furnace is also enhanced.

Having described my invention, what I claim, and desire to secure byLetters Patent, Is-

The combination, in a car provided with a steam-boiler and engine, ofsurface condensers, as D D, having air-circulating iiues CZ (Z andjoined at the top by.overhead domev E, having discharge-opening E, inwhich is provided a fan-blower G, for creating a current of air throughsaid lues CZ and enhancing the draft in the boiler-furnace,substantially as described.
